Subject [jira] [Commented] (HDFS-7853) Erasure coding: extend LocatedBlocks to support reading from striped files
Date Tue, 10 Mar 2015 00:06:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7853?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14353931#comment-14353931

Zhe Zhang commented on HDFS-7853:
---------------------------------

Thanks Jing. The 002 patch looks good to me. +1 for committing it.

I haven't done an end-to-end test with HDFS-7729 and HDFS-7782 though. I plan to file a JIRA
for comprehensive write-to-read test after these 3 pieces are in.

> We should extend {{LocatedBlocks}} class so {{getBlockLocations}} can work with striping
layout (possibly an extra list specifying the index of each location in the group)
